To allroiwmiit may concern:

Be it known that we, J Mns P. Hiorrand HA RY C; Ra'rrinomcitizens of the United States, residingat Fairview, in the county of Major and State of Oklahoma, have invented a new and useful Oil-Burning Stove, of which the following is'a specification.

The invention relates to improvements in oil burning stoves. j

The object of the present invention is to improve the construction of oil burning stoves and to provide a simple, safe, and practical heating and cooking stove, which will be free from soot and disagreeable odors, and adjustable to regulate the heat and the disposition thereof to adapt the stove for various cooking operations.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that va-- rious changes in the form, size, proportions and minor details of; "construction, .within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure l is a side'elevation of an oil burning stove constructed in accordance with this invention. Fig-2 is a vertical longitudinal sectional view of the same. Fig. 3 is a plan view partly broken away to show the top wall of the upper adjustable section of the casing; Fig. t is a horizontal sectional view on the line H of Fig. 2. Fig. 5'is an enlarged central-vertical sectional view of the starting device. Fig. 6 is a plan view of the same. Fig. 7 is a detail sectional view illustrating the construction of the combined filling device and air valve. Fig. 8 is a sectional view of the adjustable generator and spreader. Fig. 9

is a detail view of the imperforatedisk.

Fig. 10 is a detail view illustrating the arrangement of the adjusting and controlling valves. i

Like numerals of reference designate corresponding parts in all the figures of the drawings. c

In the accompanying drawings, 1n which is illustrated the preferred embodiment of the invention, the casing of the stove comprises in its construction upper and lower substantially cylindrical telescopic sections 1 and 2, constructed of sheet metal or other suitable materiahand adjustable to vary the distance between the topof the stove and an interiorly arranged burner, whereby the heating effect may bejvaried: to adapt the stove for different cooking operations. The lower section is provided at umlower end with an outwardly flared, downwardly extending flange 4c, constituting the base of the stove-casing. the casing is provided with a horizontal partition tilocated at the upper portion of the lower section and dividing the same into an upper combustion chamber 7 and a lower compartment 8 for the reception of a tank 9 for containing oil or other liquid fuel. The tank is riveted. or otherwise'secured within the lower section 2 of the casing and it is supported above the floor or other supporting surface by a base flange 4. The

horizontal partition 6, which is suitably se-.

cured at its periphery tothe inner face of the-vertical walls of the cylindrical lower section, is provided at its upper face with a lining -10 of asbestos or other suitable material, to prevent the heat from the burner affecting the contentsof' the tank 9. The lowersection is provided in its upper portion above the horizontal partition 6 with an annular series of draft inlet apertures 11," which are located in substantially the plane of the top of the burner'. i n

The upper'section, which is slidable'upwardly and downwardly on the exterior of the lower section, is provided with front and rear verticalslots 12 and has recesses or branches'l extending horizontally from the slots'and adapted. to be engaged with lugsorprojections 14 mounted on and extending'horizontally fromthe lower section at the front and back thereof. The

vertical slots 12 extend upwardly from the lower edge of the upper section, and the latter is "provided'at the rear'slot with an outwardly bowed connecting strap or piece- 15 riveted or otherwise secured at opposite sides of the rear slot and affording a rigid connection between the portions at opposite sidesof' the slot, and adaptedto prevent the upper section from spreading.

The lower branch 45, which constitutes a burner tube, is arranged upon the horizontal partition 6, and'it-extends through a starting device. The starting device consists of a horizontal bottom 4:6, a vertical outer wall 47, and an inner tube 18 extending upwardly from thebottom l6 and, surrounding the central opening 49. .The starting device is provided. with a depending supporting flange 50 consisting of an extension of the outer wall t7 and provided with ventilating openings 51. The lower branch or burner tube4t5 passes through the depending-base or supporting flange 50 andextends to a point beyond the same, and itis provided with a relatively small jet aperture :2 registering with the central opening 49 of the "startingdevice, and adapted to dis charge vaporized fuel through the same and through the inner vertical, tube +l8, the vaporized fuel or gas igniting at a pointbetween the jet aperture and the generator. The vertical connecting portion of the tube 4:4 is arranged at the back of the casing and the front terminal of the lower branch or burner tube a5 is closed by a cap or other suitable means. i

The space between the outer wall of the starting device and the inner central tube or wall 48 constitutes a cup or receptacle for oil, which is adapted to be ignited for preliminarily heating the generator sufficiently to vaporize the oil. The outer wall 47 and the inner wall or tube 48 are corrugated, and the" bottom ofthe starting cup is provided with a lining or cover of asbestos or other absorbent non-combustible material, adapted to hold a quantity of oil. The oil from the supply pipe is conducted to the starting cup by a small tube 54c, consisting of a hollow wire or other suitable material and connected at its outer end with the controlling valve '20 and coiled within the starting cup, as clearly shown in Fig. 6 of the drawings. through the outer wall 53 of the starting cup and the controlling valve is located at the front of the casing and is connected with the supply pipe at a point below the regulating valve 19. The coiled portion of the tube 54 is provided at the under side with perforations 55 to permit the oil to flow into the starting cup and spread over and saturate the absorbent lining 53. After a quantity of fuel has been allowed to flow into the supporting cup, it is ignited, and the flame therefrom will heat the generator. The adjusting valve 19 is then opened to permitthe fuel to flow into the generator,

The tube 5% extends and the vaporized fuel therefromwill pass 1 through the pipe 44: and be discharged at the jet aperture ofthe burner tube, being ignited by the flame from thestarting cup. As soon'as'thexfuel is vaporized and burns, the controlling valve 20' is closed to cut off the supply ofifuel from the starting cup;

The stove is equipped with an inclined filling tube,56 extending throughthe lower section of the casing at the front thereof and piercing the upper portion of the tank, and provided at an intermediate point with a valve seat 57. The outer portion ofthe filling tube is interiorly threaded to receive a threaded plug 58, adapted to be screwed tightly against the valve'seat to close-the opening 59 thereof. The valve plug, which is providedwith wings to enable it tobe readily turned, has a central longitudinal bore-60and is provided at the inner end thereof with a transverse passage 61 extending from the bore to opposite sides of the valve plug. The valve plug is also provided at its outer portionwith a threaded tubular extension 62, adapted to be connected with an air pump or compressor, as indicated in dotted lines in Fig.7 7 of the drawings, to enable air to be compressed within the tank for forcing the liquid fuel therefrom. The valve plug is removed from the filling tube when it isdesired to supply the tank with a quantity of fuel, and after the oil has been poured into the tank, the valve plug is replaced and is arranged a sufficient distance from the seat-to establish a communication between the interior of the tank and the transverse passage 61. This will enable the air to-be forced into the tanlnand after'a suiiicient amount of compressed air is introduced into the tank, the valve is seated, thereby closing both the opening 59 and the transverse air passage 61. The upper section of the casing is equipped with a hinged bail 63 having a suitable handle and adapted to permit the stove to be conveniently carried. The bail is adapted to swing below the top of the stove when in use.
